Gucci Envy vs. Must Essence Cartier: Which would you choose?

I've sampled Gucci Envy and was thinking of getting at least a 1.7 ounce bottle, but then I came across Must Essence, read the reviews, and it sounded even better. My questions are, which do you prefer (assuming you've tried both) and are they similar enough so that if you have one you don't really need the other?

I'll also provide some information about how I perceive these kinds of frags. Envy is like ginger set in a scented candle context. The cheapo, Corduroy is like cinnamon set in an aquatic context. I like both of them, and because the contexts are different, I like having both off them. If both had either aquatic or scented candle qualities, however, I don't think I'd feel the need for both.
